BLACKSMITHS BELLOWS.

SPECIFICATION forming part of Letters Patent No. 417,632, dated December17, 1889.

Application filed April 1889.

To all whom it may concern.-

Be it known that I, FRANK CHRISTEN, of

the city of St. Louis, in the State of Missouri,

- able construction, consisting mostly of wood.

The flexible part, which-is reduced to a minimum, is composed of flatpieces of leather with straight edges, so that there is very small wasteof material.

Figure I is a side elevation of the bellows. Fig. II is atop view. Fig.III is a detail top view, showing part of the partition and thedeflector. Fig. IV is a longitudinal vertical section at IV IV, Fig. II.

The supporting-frame has usual uprights 1, giving bearing to the pins 2,fixed in the sides of the body of the bellows. The uprights also'givebearing to the gudgeons 3 of the rock-shaft 4, to which the hand-lever 5is pivoted.

The body of the bellows is composed of a rectangular wooden box dividedby an oblique partition 6. The box has sides 7 and ends 8. The front endcontains the nozzle 9, and the rear end has the induction air-valves 10.obliquely from the lower edge of the front board 8 to the upper edge ofthe rear board 8. The air from the lower chamber 11 passes through theupwardly-opening valves 12 in the front part of the partition into theupper chamber 13, from whence it passes through the nozzle to the fire.Behind the nozzle is an inclined deflector 15, whose offlce is toequalize to some degree the current of air passing out through thenozzle, and which acts'to check the entrance of cinders or ashes intothe body of the bellows when the bottom board is descending. Thepartition 6 is made of tongued and grooved boards, so that it may expandand contract without a tendency to buckle or to leak by the opening ofthe seams. The bottom board 16 is hinged (See Fig. IV.) The partition 6extends Serial No. 306,025. (No model.)

end board 8, and has an area less than the box composing the body, sothat the bottom board may enter the lower chamber 11 and expel almostall the air therefrom. The bottom board is connected with the sides andrear end of the body by a flexible web 18 of leather.

19 is a bar secured to the bottom bybrackets 20 in such a position thatwhen the free end of the bar isin its upper position the bottom board islifted into the chamber 11 almost or quite to the partition, forcingalmost all the air from the chamber when in this position. The free endof the bar is connected by a rod 21 to the end of the hand-lever 5. Thetop board 22 is hinged to the top edge of the rear end bar 8 by aflexible strip 17, and has web-connection 18 with the side boardsand'front end board precisely like that described in relation to thebottom board, and the top board, like the bottom board, is of such asize as to be capable of entering the air-chamber and expelling almostall the air therefrom. The top board is Weighted, as usual, to give thedesired pressure to the air in the chambers 11 and 13.

I claim as my invention-- 1. A bellows having top or bottom boardconnected to the side and end boards of the body by a flexible web 18and constructed to enter the air-chamber of the body, substantially asset forth.

2. The combination, in a bellows, of the top and bottom" boards hingedto opposite ends of the body and connected to the body by the strip 17and flexible web 18, substantially as set forth.

3. The combination, in a bellows, of the oblique partition 6 and the topand bottom boards connected to the body by the flexible ,leather 18 andhinges 17 and having a smaller area than the body, all substantially asset forth.

4. The combination, in a bellows, of the body having upper and lowerair-chambers, the top and bottom boards hinged to the opposite ends ofthe body and being smaller by a flexible strip 17 of leather to thefront than and adapted to enter said air-chambers, to the opposite endsof said body, substanand the flexible webs 1S, connecting said tially asand for the purposes set forth.

bgiatillds to said body, substantially as set FRANK CHRISTEN- 5. Thecombination, in a bellows, of the \Vitnesses:

rectangular body, the diagonal partition 6 in SAML. KNIGHT, said body,and top and bottom boards hinged BENJN. A. KNIGHT.
